What system software does the tourism management major include?
Hello:
System software includes five categories: operating system, language processing program, service program, standard library program, and database management system.
1. Operating system operating system controls and manages various computer resources, automatically schedules user work programs, and handles various situations.
2. The language that a language processing program computer can recognize is not consistent with the language that a machine can directly execute. There are many languages ??that computers can recognize, such as assembly language, Basic language, Fortran language, Pascal language and C language, etc. Each of them stipulates a set of basic symbols and grammatical rules. Programs compiled in these languages ??are called source programs. A language composed of machine codes of "0" or "1" according to certain rules is called machine language. Programs written in machine language are called target programs. The task of the language processing program is to translate the source program into the target program. Source programs in different languages ??correspond to different language processing programs.
3. Service programs Service programs (also called tool software) expand the functions of the machine and generally include diagnostic programs, debugging programs, etc. Commonly used microcomputer service software programs include QAPLUS, PCTOLS, etc.
4. Standard library program class In order to facilitate users to compile programs, some commonly used program segments are usually pre-programmed in a standard format to form a standard program library, which is stored in the computer system. When needed, it is Users select appropriate program segments to embed in their own programs.
5. Database management system database management system stores large amounts of data in an organized and dynamic manner, allowing people to use these data conveniently and efficiently. Database management system is a large-scale software that manipulates and manages databases and is used to establish, use and maintain databases. There are various types of database management systems. Currently, many computers, including microcomputers, are equipped with database management systems, such as FoxPro, Sabase, etc.
